Question

In the below given circuit, the average value of output voltage is 191 V. Find the value of the power delivered to the voltage source E. Take E = 100 V and R = 5 Ω. Assume that the load current is continuous.

(a) 1.82 kW

(b) 18.2 kW

(c) 0.182 kW

(d) 18.2 W

The question was asked in unit test.

My enquiry is from Single Phase Semi-Converters-3 in section Converters of Power Electronics

Answer 1

Correct choice is (a) 1.82 kW

For explanation: Note that as the load current is continuous, L can be neglected.

Vo = 191V.

Io = Vo-E/R = 191-100/5 = 18.2A

P = E x Io = 100 x 18.2 = 1.82 kW.
